Steve McClaren's FC Twente have suspended Theo Janssen for two months and fined the midfielder after he was involved in a car crash under the influence of alcohol.
Janssen was driving when his car was involved in an accident after the match against Vitesse Arnhem on 21st November, with one of his passengers hospitalised with injuries.
A blood test carried out by police after the crash, in which Janssen suffered a broken nose and minor cuts and bruises, revealed excess alcohol in his system.
Eredivisie leaders Twente have therefore decided to act and the club have issued a statement saying they are "very strongly disappointed" by Janssen's actions.
Chairman Joop Munsterman said: "It is unacceptable for a professional footballer to drink and drive. It endangered himself and those around him.
"Also, a footballer has to be aware that he is a role model to young people."
The statement said: "In consultation with FC Twente, Theo Janssen has decided to impose the maximum fine on himself within the player's contract."
The club also said the player, whose fine will go to charity, will be suspended from club competitions "for a period of two months until 31st January, 2010" and work at a rehabilitation centre for victims of car crashes.
"I have been extremely stupid," Janssen told his club's official website. "I had been drinking beer after the game to celebrate the victory then still got into the car.
"It should never have happened."
As for his punishment, Janssen added: "I have harmed the name of FC Twente and football. I'm willing to do anything to make amends."
